“…Such non-linear behaviours have been known since the 1960s. 24,63,65,66 Different mechanisms have been proposed to describe ablation in each of these regions. For example, region 1 may be dominated by thermal effects, region 2 by plasma absorption, region 3 by phase explosion, and region 4 by high energy plasma.…”

“…The number of particles and their size distribution also depends on the laser irradiance, as well as wavelength, fluence, ambient gas and pressure, and properties of the sample. 24,31,35,36,55,[67][68][69][76][77][78] The particle influence on fractionation and analytical performance is a critical area that needs to be thoroughly investigated.

“…There was a tremendous body of literature on laser ablation using other excitation sources before ICP-MS. High-voltage sparks, 11 microwave plasmas, 12 direct current plasmas, 13 graphite furnaces 14 and ICP-AES have been used as excitation sources with laser ablation. [15][16][17][18][19][20][21][22][23][24] Today, the two prevalent laser ablation technologies for solid sampling are inductively coupled plasma mass spectrometry (LA-ICP-MS) and laser-induced breakdown spectrometry (LIBS). For both these technologies, a focused laser beam converts a tiny portion of a solid sample into a vaporphase aerosol.…”

This paper presents a brief overview of the current research issues in laser ablation for chemical analysis, discusses several fundamental studies of laser ablation using time-resolved shadowgraph and spectroscopic imaging, and describes recent data using femtosecond ablation sampling for ICP-MS and LIBS. This manuscript represents a summary of the plenary lecture presented at the 2004 Winter Conference on Plasma Spectrochemistry.

“…These conditions have been verified by Chan & Russo (Chan & Russo, 1991) and Corsi et al (Corsi et al, 2000) and it is understood how to realize these conditions analytically. The use of LIBS for elemental detection is simple and readily accomplished via peak matching against a spectral library constructed in advance for a specific application.…”

“…In this study, precise control for the elemental composition in the vapor plume is very important. Thus, stoichiometric ablation, in which 9 W/cm 2 is sufficient for silicates and plastic materials to achieve stoichiometric ablation (e.g., Chan and Russo, 1991;Russo, 1995;Mao et al, 1996). Entropy gained by laser irradiation with such laser intensity is estimated to be equal to the entropy gained by hypervelocity impacts at velocities between several tens of km/s and a hundred km/s (Kadono et al, 2002;Sugita et al, 2003Sugita et al, , 2012.…”

Oxidation of carbon compounds by silica-derived oxygen within impact-induced vapor plumes

et al. 2013

Impact-induced vapor plumes produce a variety of chemical species, which may play an important role in the evolution of planetary surface environments. In most previous theoretical studies on chemical reactions within impact-induced vapor plumes, only volatile components are considered. Chemical reactions between silicates and volatile components have been neglected. In particular, silica (SiO 2 ) is important because it is the dominant component of silicates. Reactions between silica and carbon under static and carbon-rich "metallurgic" conditions (C/SiO 2 1) are known to occur to produce CO and SiC. Actual impact vapor plumes, however, cool dynamically and have carbon-poor "meteoritic" composition (C/SiO 2 1). Reactions under such conditions have not been investigated, and final products in such reaction systems are not known well. Although CO and SiO are thermodynamically stable at high temperatures under carbon-poor conditions, C and SiO 2 are stable at low temperatures. Thus, CO may not be able to survive the rapidly cooling process of vapor plumes. In this study, we conduct laser pulse vaporization (LPV) experiments and thermodynamic calculations to examine whether interactions between carbon and silica occur in rapidly cooling vapor plumes with meteoritic chemical compositions. The experimental results indicate that even in rapidly cooling vapor plumes with meteoritic compounds are rather efficiently oxidized by silica-derived oxygen and that substantial amounts of both CO 2 and CO are produced. The calculation results also suggest that those oxidation reactions seen in LPV experiments might occur in planetary-scale vapor plumes regardless of impact velocity as long as silicates vaporize.
